SPECIFICATION formingpart of Letters Patent No. 277,825, dated May 15, 1883.

Application filed January 30, 1883'.

To all whom it may concern Beit known that I, HENRY GATE ATKINSON, of Franklin, in the county of Simpson and State of Kentucky, have invented a new and 5 useful Improvement in'Railway-Gar Axles, of which the following is a full, clear, and exact description, reference being bad to the annexed drawings, forming part of this specification.

The object of this invention is to provide a 1o railway-car axle having removablejournals, in

order that when the journals become worn the axle may be repaired by placing new journals thereon and the invention consists in the construction hereinafter described and clai med. 15 In the drawings, Figures 1 and 2 are elevations, partly in section, showing removable journals or thimbles for car-axles, formed, re spectively, in one and two parts.

A indicates an axle having the ends 13 B, 20 outside the wheels 0 0, reduced, and provided with a male thread, D. Over these reduced and externally-threaded portions a pair of internally-threaded thimloles, E E, are screwed to form journals. I prefer to form the thim- 25 ble E in two parts, 6 0 as shown in Fig. 2,

and provide the axle A with two reduced portions, b b, at the ends, which portions are of difi'erentdiameters, and are formed with might and left hand thread, respectively, in order that 0 the parts 0 0 may be screwed thereon in opposite directions. With this construction the said parts 0 0 will be adapted to serve asjamnuts to each other, so that the movement of the car in either direction will cause the parts (No model.)

to bind, and thus prevent them from becoming 5 loose. The thimbles E are formed with collars e e at the ends, and may also be provided with diametrical perforations f, which are adapted to register with corresponding perforations, g, in the reduced parts of the axlc,inoro der that, when they are screwed on, a rivet may be inserted and riveted in the perforations to prevent the thimbles from becoming unscrewed by the motion of the axle. The rivets are shown at h. tersunk at the outer surface of the thimbles, to provide a smooth surface when the ends of the rivets h are headed therein.

With the above construction an axle may be used for an indefinite period, since thejour- 50.
